The first time Asta met Fanzell Kruger was shortly after he received his grimoire. In order to train with his new anti-magic sword, Asta holes up in the woods and meets Fanzell, who is looking for his missing fiancée, Dominante Code. Fanzell uses wind magic and is able to turn wind into a sword so he helps Asta train. One day while they’re in the forest, someone comes for Fanzell’s life...
To make a surprise attack, you must 
have three times the enemy's strength.
،عند توجيه هجوم مباغت
 .علينا أن نملك ثلاثة أضعاف قوّة العدوّ
Für Überraschungsangriffe muss man das
Dreifache der Truppen des Gegners bereitstellen.
"Prepara el triple de gente
cuando ataques por sorpresa.
"Prepara el triple de gente
cuando ataques por sorpresa.
Pour une attaque-surprise,
trois fois plus de soldats que l’ennemi.

tre volte superiori a quelle del nemico.
Se vai fazer um ataque surpresa,
Для успешной засады
надо втрое превосходить врага.
